Protecting Your Mobile from Spam: Troubled by spam calls? File a complaint in minutes using TRAI's DND app

Protecting Your Mobile from Spam: Many people frequently complain about receiving unwanted promotional calls and spam messages, forcing them to block the numbers. However, blocking just one or two numbers does not completely eliminate the problem. You will be pleased to know that there is a solution: TRAI (Telecom Regulatory Authority of India) has launched a dedicated app called the TRAI DND app. Through this app, you can file complaints about spam calls and messages directly from your phone in just a few seconds. That is why TRAI urges people not to overlook this issue. Simply blocking a number only stops the nuisance from reaching you—and often only temporarily—so filing a formal complaint via the app is the better approach. Let us take a closer look at this app and how it works.

Why is it important to file complaints on the TRAI DND app?

TRAI states that merely blocking a number on your phone does not stop spam calls at the source, as spammers often acquire new numbers and resume calling. Consequently, TRAI has issued an advisory urging the public to file complaints about spam calls and messages directly through the DND app to help resolve the issue. According to TRAI, based on user complaints, over 2.1 million mobile numbers and approximately 100,000 companies involved in sending spam and fraudulent messages have been blacklisted so far. This demonstrates that the more complaints filed, the more effectively such fraudulent companies can be curbed. In February 2026, TRAI launched a revamped—meaning new and upgraded—version of its DND app. TRAI Chairman Anil Kumar Lahoti stated that this new version features a user-friendly interface, multi-language support, faster complaint registration, and improved complaint status tracking. Additionally, users can report spam directly from their call logs or message lists, making the process significantly faster than before.
